Themonitor controller 10 can be a traditional monitor host or a personal computer provided with operation system and monitor controlling software. The latter enables expediency and lower cost of expanding equipment. Thevideo server 141 is used for controlling thevideo camera set 151 and themicrophone 161 electrically connected thereto, and is used for transmitting data to thevideo camera set 151 and themicrophone 161. The video camera set 151 and themicrophone 161 are arranged at given positions according to the requirements of installation. The video camera set 151 and themicrophone 161 are electrically connected to thevideo server 141, respectively, which enables thevideo server 141 to control and receive data from thevideo camera set 151 and themicrophone 161. Data received by thevideo server 141 can be converted and transmitted out by thevideo server 141. Thevideo server 141 is capable of connecting more than one set of video camera set and microphone synchronously. For example, thevideo server 141 is capable of connectingvideo camera sets microphones video server 142 can be added to the system to control and receive data from avideo camera set 153 and amicrophone 163. Quantity of the video camera sets or the microphones is determined according to the factual requirement. Other examples of different quantity of video camera sets and microphones will no more be recited in this embodiment repeatedly. - According to the above-mentioned configuration, the
monitor controller 10 must be electrically connected to a first powerline LAN switch 121, and afirst video server 141 should electrically connected to a second powerline LAN switch 122. If necessary, asecond video server 142 should be electrically connected to a third powerline LAN switch 123. It is noted that the powerline LAN switches power line LAN 18. Thus, controlling instructions sent out by themonitor controller 10 can be converted into network packages by the first powerline LAN switch 121, and the network packages are transmitted to a given position, such as the second powerline LAN switch 122 and the third powerline LAN switch 123, via thepower line LAN 18. The second powerline LAN switch 122 and the third powerline LAN switch 123 receive the network packages and then convert the packages into controlling instructions for transmitting to the first andsecond video servers microphones microphones second video servers power line LAN 18 via the second and third power line LAN switches 122, 123, and finally the packages are received and converted into data by the first powerlien LAN switch 121 for transmitting to themonitor controller 10 to handle, which achieves the purpose of exchanging data by thepower line LAN 18. A user can obtain needed information from themonitor controller 10 for vigilance. In a better mode, thepower line LAN 18 should contain no filter for preventing the network packages form being filtrated during the transmitting procedure. - The video camera sets 151, 152, 153 and
microphones - An input port of a generic power line LAN switch is matchable to a RJ-45 cable plug, at the same time, a generic video server provides a RJ-45 cable plug, which makes the connection between the power line LAN switch and the video server more easier. The cost for connecting the power line LAN switch and the video server is also very low. Indeed, the monitor controller and the first power line LAN switch can be simultaneously arranged on one printed circuit board for obtaining a function-combined equipment, which enables lower cost and more convenient usage. For the same reason, the first video server and the second power line LAN switch can be also simultaneously arranged on one printed circuit board, while the second video server and the third power line LAN switch can be also simultaneously arranged on one printed circuit board. In addition, the video camera sets and the microphones only need to be connected to power lines, which enables to reduce other complex arrangement of cables and enables to beautify the appearance of the system after installation. All these can further satisfy the users' requirements.
